Associated PressThe Raiders may not have given up on JaMarcus Russell yet, but Joe Theismann has.The Oakland Raiders may give JaMarcus Russell another shot to prove he's an NFL quarterback, but Joe Theismann has seen enough.

The former Washington Redskins quarterback ripped the former Williamson High and LSU star on Sirius NFL radio on Wednesday, as reported on NFL.com, and suggested that the Raiders, who showed interest in Donovan McNabb, go after the quarterback McNabb will replace in Washington, Jason Campbell.

“If I was the Oakland Raiders, I would be on the phone with (Redskins GM) Bruce Allen and see what kind of deal we could make for Jason Campbell," Theismann said. "Because I can tell you conclusively that JaMarcus Russell will never be able to play quarterback in the National Football League.

Theismann's quote about Russell's weight is interesting, since reports out of Oakland last month indicated he'd reported to workouts in better shape than last year after working out for a month or so at a training facility in Arizona.

The Oakland Tribune's Steve Corkran reported in March that Raiders director of squad development Willie Brown raved about Russell in an interview with Raiders play-by-play announcer Greg Papa on Comcast Sports.

"It's quite a bit of weight that he's lost," Brown said. "I don't want to pin it down and say how much he lost, but it will be a significant difference when you see him compared with last year. The most important thing is he's getting in shape. Not only losing weight but getting in shape."

Raiders head coach Tom Cable said in an interview with NFL.com that he expects Russell to be part of a "full, wide-open competition" for the Raiders' starting job.

"He's doing fine," Cable said. "The fact that he's there working now with his teammates I think is really, really important. It gives him a chance now to, when we start practice, go and compete for the job with the other quarterbacks."

Memo to Campbell: If anyone in black and silver approaches you with a contract in their hand, don't walk -- run. As far as you can. And don't stop running. With apologies to Detroit and Cleveland, Oakland may be the only franchise in the league more dysfunctional than Washington the last few years.
